EditorWindow.BeginWindows

説明

すべてのポップアップウィンドウを表示するための開始領域をマークします

GUI.Window behaves somewhat differently in the editor than inside your games. In games, GUI.Window pops up a window on your screen. In the editor, GUI.Window shows a subwindow inside one of your editor windows. Begin/EndWindows is used to determine where these can go. You need to have all calls to GUI.Window or GUILayout.Window inside a BeginWindows / EndWindows pair. Like this:


Simple editor Window with a window and a button inside.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class GUIWindowDemo : EditorWindow {
    // The position of the window
    public Rect windowRect = new Rect(100, 100, 200, 200);
    void OnGUI() {
        BeginWindows();

        // All GUI.Window or GUILayout.Window must come inside here
        windowRect = GUILayout.Window(1, windowRect, DoWindow, "Hi There");

        EndWindows();
    }

    // The window function. This works just like ingame GUI.Window
    void DoWindow(int unusedWindowID) {
        GUILayout.Button("Hi");
        GUI.DragWindow();
    }

    // Add menu item to show this demo.
    [MenuItem("Test/GUIWindow Demo")]
    static void Init() {
        EditorWindow.GetWindow(typeof(GUIWindowDemo));
    }
}

The placement of the BeginWindows / EndWindows pair determines where popup windows will appear; all windows are clipped to the clipping area defined by GUI.BeginGroup or GUI.BeginScrollView. A small example of that


Simple editor window with a window and a button inside using scroll bars.

using UnityEditor;
using UnityEngine;
using System.Collections;

public class GUIWindowDemo2 : EditorWindow {
    // The position of the window
    public Rect windowRect = new Rect(100, 100, 200, 200);
    // Scroll position
    public Vector2 scrollPos = Vector2.zero;
    void OnGUI() {
        // Set up a scroll view
        scrollPos = GUI.BeginScrollView(new Rect(0, 0, position.width, position.height), scrollPos, new Rect(0, 0, 1000, 1000));

        // Same code as before - make a window. Only now, it's INSIDE the scrollview
        BeginWindows();
        windowRect = GUILayout.Window(1, windowRect, DoWindow, "Hi There");
        EndWindows();
        // Close the scroll view
        GUI.EndScrollView();
    }
    void DoWindow(int unusedWindowID) {
        GUILayout.Button("Hi");
        GUI.DragWindow();
    }
    [MenuItem("Test/GUIWindow Demo 2")]
    static void Init() {
        EditorWindow.GetWindow(typeof(GUIWindowDemo2));
    }
}
